Digital manufacturing has become more popular in today's manufacturing industries. From 3D computer-aided design model to a physical part, digital manufacturing provides a way to reduce the manufacturing cost, in terms of labor hour, reduction in material scrap, good processing quality and repeatability of process. On the other hand, to create a 3D virtual model of an existing physical part is very important for validation, inspection, quality control, non-destructive testing, product development and numerical simulation (Finite Element Analysis / Computational Fluid Dynamics). This proposal requests a portable 3D scanner –MetraSCAN 3D from local company—Creaform Inc. to create a manufacturing database and obtain a model in a usable format such as a triangular-faced mesh, a set of NURBS surfaces or a CAD model. Compared to the other methods such as conventional CMM, the requested MetraSCAN is free of any rigid measurement setup. It can provide shop floor measurement accuracy that is robust to the instabilities of the environment. It can also provide fast 3D modeling and help tooling and jig development. With the MetraSCAN, the user can carry out finite element analysis and numerical simulation of the part. The requested 3D scanner has extendable measurement volume, high speed and usable data that can be easily and dynamically extended without loss in accuracy or conventional leapfrogs. Hence, it can improve the flexibility and efficiency of the production process. The measurement accuracy is up to 0.020mm, which can satisfy the requirement of the applicants' research projects. The results of the equipment will advance the manufacturing techniques of composite structure from mandrel design, on-line AFP fiber placement, and the analysis of composite structure and damage detection of the manufacturing composite. The potential for major advances is the digital manufacturing technology development for composite manufacturing and other aerospace robotic manufacturing systems such as drilling, riveting and deburring systems.
